How would you measure the success of Facebook Save feature?

Introduction

Measuring the success of Facebook's Save feature requires a comprehensive approach that considers multiple stakeholders and metrics. To effectively evaluate this product success metric problem, I'll follow a structured framework covering core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context (5 minutes)

Facebook's Save feature allows users to bookmark content they want to revisit later. This includes posts, photos, videos, and links shared on the platform. The primary stakeholders are:

1. Users: Seeking to easily save and retrieve content of interest
2. Content creators: Aiming for increased engagement and reach
3. Facebook: Looking to boost user engagement and time spent on the platform
4. Advertisers: Interested in increased ad exposure and targeting opportunities

User flow:

1. User encounters interesting content while scrolling
2. Clicks "Save" button or selects "Save" from post options
3. Content is added to their saved items list
4. User can access saved content later through their profile or dedicated "Saved" section

The Save feature aligns with Facebook's broader strategy of increasing user engagement and time spent on the platform. It also provides valuable data on user interests, which can be used for content recommendations and ad targeting.

Competitors like Twitter (Bookmarks) and Pinterest (Pins) offer similar features, but Facebook's implementation is more integrated into its core newsfeed experience.

Product Lifecycle Stage: The Save feature is in the maturity stage, having been introduced several years ago and widely adopted by users. The focus now is on optimizing and expanding its functionality.
